Operation
Fluid Voltage Discharge and
Grounding Procedure
WARNING
Electric Shock Hazard
The fluid supply is charged with high volt-
age until the voltage is discharged. Contact
with the charged components of the isola-
tion system or spray gun electrode will
cause an electric shock. To avoid an electric shock,
follow the Fluid Voltage Discharge and Grounding
Procedure:
• whenever you are instructed to discharge the
voltage
• before cleaning, flushing, or servicing the system
equipment
• before approaching the front of the gun
• or before opening the safety enclosure for the
isolated fluid supply.
1. Turn the ES ON/OFF valve OFF and wait 30 sec-
onds.
2. Remove the door T-handle locking screw. This will
shut off the air to the gun and trigger the grounding
cylinder to discharge any remaining electrical
charge.
3. Use the grounding rod to touch the pump and sup-
ply pail. If you see any arcs, see Electrical Trouble-
shooting on page 39.

Pressure Relief Procedure

Pressurized Equipment Hazard
The system pressure must be manually
relieved to prevent the system from starting
or spraying accidentally. To reduce the risk
of an injury from electric shock, accidental spray from
the gun, splashing fluid, or moving parts, follow the
Pressure Relief Procedure whenever you:
• are instructed to relieve the pressure
• stop spraying
• check or service any of the system equipment
• or install or clean the fluid nozzle.
1. Turn the ES ON/OFF valve OFF.
2. Follow the Fluid Voltage Discharge and Ground-
I ES O
ing Procedure at left.
3. Turn off the main air supply valve (B).

4. Trigger the gun into a grounded metal waste con-
tainer to relieve the air and fluid pressure.
5. Relieve fluid pressure in the fluid supply unit as
instructed in your fluid supply unit manual.
